Description

Terminal plug wire pulling device

Technical Field

The utility model relates to the field of fastener disassembly, in particular to a puller.

Background

In order to prevent the wire harness from falling off after being inserted into the terminal and causing poor line contact, the wire harness head in the wire harness terminal is mostly provided with an anti-falling clamping structure, namely, the wire harness cannot be reversely pulled out after being inserted from one side of the terminal.

However, in the daily production process, it often happens that a worker assembles an incorrect wire harness into an incorrect terminal head, and at the moment, the wire harness is very difficult to be pulled out again, which affects the production efficiency.

In order to achieve the purpose, the utility model adopts the technical scheme that:

the utility model provides a terminal plug wire pull-out ware, includes handle, thimble and awl head, still includes:

a cavity disposed within the handle;

the thimble consists of a thimble fixing part, a thimble sliding part and an ejection part, the thimble fixing part is fixed at the bottom of the cavity, and the ejection part arranged on the thimble sliding part extends out of the handle from one end of the cavity;

the conical head consists of a conical head, an accommodating cavity arranged in the conical head and a pulling cavity arranged in the conical head, the conical head is sleeved from one side of the cavity to the inner direction of the cavity, and the ejection part is inserted into the pulling cavity through the accommodating cavity;

the spring is arranged in the cavity and the accommodating cavity, one end of the spring abuts against the end part of the accommodating cavity, and the other end of the spring abuts against the thimble fixing part.

In a preferred embodiment of the utility model, the cavity is recessed inwardly from a side of the handle.

In a preferred embodiment of the present invention, the outer diameters of the thimble fixing portion, the thimble sliding portion and the ejecting portion are sequentially increased gradually.

In a preferred embodiment of the utility model, the handle is further provided with a tightening screw, the lower end of the tightening screw faces the conical head, and the tightening screw can apply friction force to the surface of the conical head so as to adjust the moving speed of the conical head.

In a preferred embodiment of the utility model, the distance between the tightening screw and the outer edge of the handle is 13 mm.

In a preferred embodiment of the utility model, the tightening screw is of the national standard M4.

In a preferred embodiment of the present invention, the spring is made of steel.

In a preferred embodiment of the present invention, the handle is made of nylon.

The utility model has the beneficial effects that:

according to the terminal plug wire puller provided by the utility model, the wire harness head in the wire harness terminal is rapidly pulled out through the matching of the pulling cavity and the ejector pin, so that the reworking efficiency is improved.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below.

FIG. 1 is a diagram of the structure of the product of the present invention.

Detailed Description

In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The detailed structure of the present invention will be further described with reference to the accompanying drawings and the detailed description.

Referring to fig. 1, a terminal plug wire extractor mainly includes a handle 10, a thimble 20 disposed in the handle 10, and a taper head 30 disposed between the thimble 20 and the handle 10.

The handle 10 is provided with a recessed cavity 11. The thimble 20 is composed of three sections of thimble fixing part 23, thimble sliding part 22 and ejecting part 21 with gradually decreasing outside diameter. The thimble fixing portion 23 is fixed to the bottom of the cavity 11, and the ejector portion 21 provided on the thimble sliding portion 22 projects outwardly from one end of the cavity 11 of the handle 10. The conical head 30 is composed of a conical head 32 on the left side, a receiving chamber 33 arranged inside the conical head 30 and a pulling chamber 31 arranged inside the conical head 32. The conical head 30 is inserted from one side of the cavity 11 to the inside of the cavity 11, so that the accommodating cavity 33 and the cavity 11 are communicated and jointly form a cavity. The ejector 21 is inserted into the pull-up chamber 31 through the accommodation chamber 33. And a spring 40 disposed in the cavity 11 and the accommodating cavity 33, wherein one end of the spring 40 abuts against the end of the accommodating cavity 33, and the other end abuts against the needle fixing portion 23. The handle 10 is further provided with a tightening screw 12, a lower end of the tightening screw 12 faces the bit 30, and the moving speed of the bit 30 can be adjusted by applying a frictional force to the surface of the bit 30 by tightening the tightening screw 12. In order to prevent interference, the distance between the tightening screw 12 and the outer edge of the handle 10 is 13mm, and the tightening screw 12 is preferably national standard M4. The material of the spring 40 is steel, preferably 65 Mn. The handle 10 is made of nylon.

When the wiring terminal is used, an operator holds the handle 10 tightly, inserts the conical head 30 into the wiring hole of the wiring terminal, and the wiring harness head in the wiring hole is completely sleeved in the pulling cavity 31. At this time, the cone 30 is gradually retracted into the handle 10 when an external force is applied, and the ejector 21 gradually moves to the outside of the pull-up cavity 31, and finally abuts against the harness head to eject the harness head from the terminal. After the operation is finished, the conical head 30 is reset under the action of the spring.
